The Age Differences in Relationships

I didn't realize that Ellen and Ben have such a big age difference in between them. Yeah he's like supposed I think he gets age differently at different points or at least suggested age is different. And then in book two they start this weird thing which was not in book one at alllike not reference not not hidden like nothing. All of a sudden there's this like question that's brought up several times of Ben's relationship with Kelsey.
